More Energy by Design

LG Chem ESS Battery

Optimized Solution for Energy Saving & High-quality Power

Energy Storage System (ESS) stores electric energy and utilizes it for later consumption. This battery is purposed to improve energy efficiency by enhancing the quality of renewable energy that results in the stabilization of the power supply system. LG Chem provides the most optimal energy solution for the users using our state-of-the-art energy storage system with a long lifespan and a top-notch quality.

The differentiated technology and outstanding performance of LG Chem's ESS battery make it like no other battery on the market. It applies Lamination & Stacking technology to create high energy density and achieved compactness. It also maintains a stable structure against frequent charging/discharging, with a superior lifespan compared to its competitors.

Concept of the Energy Storage System (ESS)

The No. 1 Li-ion Battery ESS Company in the World

LG Chem is leading the global ESS market with successes in various ESS projects, and its track record is rapidly growing

Battery Management System(BMS) with High Reliability

ESS battery requires BMS with level is divided into Module BMS, Rack BMS, and Bank BMS according to its application. LG Chem successfully developed a BMS based on its proprietary technology and has achieved the highest level of safety through an integrated management from battery cells to its entire system.

California's SGIP rebate program can help you save on Energy Storage


The California energy storage rebate program, technically referred to as the Self-Generation Incentive Program (SGIP), was established back in 2001. SGIP supports a variety of “behind the meter” technologies that are installed at your home or business, including energy storage, fuel cells, and combined heat and power generators.


Until recently, the process of applying to get a home battery rebate through SGIP was difficult, particularly for residential customers. Luckily for homeowners with energy storage in California, the program is getting an overhaul. There are a few changes that will lead to major incentives for CA home batteries.

First, and most importantly, homeowners who are customers of either PG&E, SCE, or SDG&E will be eligible for an incentive as high as $500 per kilowatt-hour (kWh) when you install a home battery. That’s enough to cover most, if not all, of your costs. The value of the per-kWh incentive depends on the size of the battery you purchase and will be reduced as more batteries are installed in the Golden State, so it pays to be an “early adopter” of home batteries.

StorEdge™ Products for On-grid Applications & Backup Power

SolarEdge’s StorEdge™ DC coupled storage solution automatically provides homeowners with backup power in case of grid interruptions and allows home owners to maximize self-consumption and to enable energy independence.

The StorEdge™ solution for on-grid applications and backup power is based on the following products:

Single Phase Inverter for On-grid Storage and Backup Power
The SolarEdge single phase inverter for on-grid applications and backup power manages the battery and the system energy, in addition to its traditional functionality as a DC-optimized PV inverter.
  • Backup Power – inverter includes the hardware required for automatic backup power for backed-up loads in case of grid interruption
  • On-grid Applications – maximizes self-consumption through export limit feature and time of use shifts for reduced electric bills
  • Simple Design and Installation – single inverter for PV, on-grid storage, and backup power
  • Enhanced Safety – designed to eliminate high voltage and current during installation, maintenance, and firefighting
  • Full Visibility – built-in monitoring of battery status, PV production, remaining backup power, and self-consumption data
  • Easy Maintenance – remote access to inverter software
SolarEdge Meter

The SolarEdge meter is used for battery integration and for production / consumption readings for Export Limitation.
